High density data storage device and data recording or reproduction method using the same

Abstract

A high density data storage device and a data recording or reproduction method using the same, which can record or reproduce high density data without contact, thereby preventing data errors due to contact are provided. The high density data storage device uses a recording medium and a probe. The recording medium is a thin film made from phase change material or oxide resistance change material, and the probe has a tip formed in a lower portion thereof, which moves with a spacing from the top of the recording medium. Further, recording or reproduction of data is performed through electric field or heat emission, which is generated in the tip of the probe, without direct contact between the recording medium and the probe, so that it is possible to remove instability caused by contact between the recording medium and the probe and to stably record or reproduce data in or from the recording medium without errors.

Benefits of technology

[0025]According to another aspect of the present invention, there is provided a high density data recording or reproduction method comprising both a recording medium formed as a thin film on a lower electrode and a probe moving with a spacing from a surface of the recording medium, the method comprising: moving the probe with the spacing from the surface of the recording medium;

Problems solved by technology

However, since the solid-state memory device only has a capacity of several tens of GB, it is difficult to use the solid-state memory device as a large
